回答1:

I had the same issues.

I've fix it with X row.. force to break-page.

it's just because the pdf try to output a lot of row and he can't jump to the next page.

In your case, try to place an :

 page-break-after: always;

on the first tr..

<tbody> 
      <?php $x='a';while($rw2<$rsummary): $rw3 = 0;?>
      <tr style="page-break-after: always;">

or you can make a php to do that after X line.

I hope that will be useful for someone.

Best regards,

===== EDIT =====

Also, remove the "border-collapse" on your table.

回答2:

This happens when a table extends beyond the size of the paper.
You can use a custom paper size. It will solve the problem.

Example :

$paper_orientation = 'landscape';
$customPaper = array(0,0,950,950);
$dompdf->set_paper($customPaper,$paper_orientation);

回答3:

I have been facing the same problem for days, in a huge table with rowspan and colspan, but no border-collapse:collapse (there is a known issue related to that property).

I have resolved it by adding this to the style of my table element:

table
{
   border-collapse:unset;   
}

Hope it helps!

回答4:

I had the same issues. Make sure you don't have any external css or any other linked file. However i fixed it by completely designing the PDF file through internal css and inline css. I hope it solve your problem.

回答5:

This could be solved when closing the tables several times. Then tables fits to the paper size ant the error is gone.
